POTS & barometric pressure


Recommended Posts

I have been trying to figure out why POTS can worsen with weather changes ( as it does in my case ).  According to this article found online

https://migraineagain.com/feel-4-ways-barometric-pressure-affects-health/

I found that barometric pressure affects migraines, BP, blood sugar levels and joints.  It can cause vasoconstriction - and the drop in blood sugar can cause fatigue.  Most importantly the article states that when the barometric pressure drops it causes the blood viscosity to increase. That might be the clue - thicker blood will trigger POTS. This would explain why in some of us our symptoms worsen in certain seasons ( spring and fall in my case ). I usually experience a sudden onset of POTS symptoms like severe fatigue, BP fluctuations leading to syncope, increase in orthostatic intolerance … all improved by IV saline. This explains why in many of us IV fluids are so helpful - they improve the blood viscosity!!! 

I find this very enlightening and an explanation as to the reasons behind seasonal flares. -- I also have found that allergies cause flares in me due to the effects of histamine release ( vasodilation ), this includes seasonal allergies ( spring, fall ) as well as insect bites and rashes ( summer ). 

does this ring a bell for anyone?

Defiantly ! Stormy weather gives me migraines . I have allergies which induce asthma and facial swelling, rashes etc if I don’t remember to take my antihistamines. Last year I was a bug magnet and their bites lasted weeks , they never use to like me so something has changed in my body I reckon.

Yes, low barometric pressure makes everything worse for me too. This is one reason I moved to the sunny southwest!

Well - I have found the barometric pressure to definitely be a cause. I have been feeling very well in my home at 2500 feel elevation in the Appalachian mountains. The spring temps helped a lot in being able to get around and feel almost normal. I was doing so well that I agreed to go on short trip to the ocean with my family. Long story short - as soon as I got out of the car after a 7 hour drive POTS came back full force: palpitations, cold hands and feet, inability to be up for long, fatigue, diarrhea … I had to stay in the airconditioned room all day and only could venture out in early mornings and after sun set. 

Thank god I have a port and brought my IV stuff with me. The second day I gave myself a liter of fluids and felt much better, even able to stroll briefly on the beach. 

So - this is just simply proof for me that even after a very long good spell we are not really over anything - with the right meds, staying within our limitations and avoiding triggers we can manage - but as soon as we venture off it's back to square one!!!! 

However - I would like to add that without fluids handy I would not have been able to go at all - and it is very important to my family to make vacation memories with me. So I am grateful for the port and the ability to have fluids available anytime I need them. So sad that IV fluids are still not a known go-to fix for acute flares. A port is not needed unless they are given weekly or daily, so everyone should just be able to walk into a clinic or ER, mention POTS and get a bag.

Hello. I seem to have trouble with downward changes rather than absolute pressure.

But in general this pattern holds:

Rainy weather = feel relaxed or sedated and less able to work. High pressure = more energy, sometimes too much.

I know that weather definitely affects me, too. My major point is about how frowned upon fluids still are in mainstream medicine. It’s like you’re asking for morphine with most doctors. It makes no sense to me - they don’t offer alternatives, and no one ENJOYS getting IV fluids!
